1lean 2 rich cylinders

let me take a guess compression diff,coil diff, valve clearance diff,leaky injectors,throttle plate diff,debris in injectors. after you check out these i will come up with some more:sneaky::banghead:
if it was running you might be able to use a thermal gun to see the diff.
Thanks mate yes will start with the exhaust management , the comp and valve shimming ,next week when I change the plugs as regular service. I pulled secondary throttle plates when ran 3K N filters and re mapped it kept original headers and ran 57cm dia ,mega phone muffler.
 
sorry i was just being a hard a$$.
but a comp test would tell you if the valves were not closing all the way.
i think that if the main throttle plates are out of sink you may get a diff there.
check the hoses going into the map sensor.
